PTFE Compression Molds

Bush, Billet and Sheet Dies for PTFE Powder Presses

In-house PTFE compression moulds matched to HEMSUN presses. Quoted examples include a Ø500 × 100 mm ID × 600 mm hollow-billet die (3-piece split cavity, carbon steel with zinc plating), an SS-304 Ø150 × 60 mm ID × 100 mm billet die with lifting handle, a 550 × 550 × 10 mm two-piece sheet die, EN-31 3-cavity bush dies, and manual bush cavities such as Ø39 × 20 × 120 mm. Multi-cavity layouts (for example five cavities on Ø35 mm bush) are designed with the press.

Applications

Hollow and solid PTFE billet moulds
Bush and rod compression dies

Frequently Asked Questions

What PTFE die sizes have you built?

Examples include a Ø500 × 100 mm ID × 600 mm hollow-billet die (3-piece split cavity, carbon steel with zinc plating), an SS-304 Ø150 × 60 mm ID × 100 mm billet die with lifting handle, a 550 × 550 × 10 mm two-piece sheet die, EN-31 3-cavity bush dies (OD 73 × ID 46 × 42 mm), and manual bush cavities such as Ø39 × 20 × 120 mm.

Can you make multi-cavity PTFE bush dies?

Yes. Five cavities are practical on a Ø35 mm bush with the 35 Ton fully auto press. Cavity count depends on OD, press tonnage, and fill method.
